Cannot see terms in Multiterm...

...but I can see Termbase features (about/statistics/status) and term recognition works in Trados.

I get the following error messages when trying to open a Termbase : "Impossible to establish a connection to unknown SDL MultiTerm server" and then "Failed to activate view Termes".

It happens on all my Termbases and didn't use to happen before. I've tried to re-install Multiterm but with no effect... Any ideas ?
